Update to the newest alpha code. I have 029k running on the bench (car is down) with MT 756.

The other cool thing about the newer alpha releases is that they support real-time barometric correction - you need a second MAP sensor identical to the one hooked up to the manifold, though. It works on the bench but I haven't tried it on the car yet. I might end up putting a "large" (0.1-1.0 uF) capacitor across the second MAP sensor output to average the output more. It seems to fluctuate around 99-100 or 100-101 kPa very quickly at times, where as actual barometric pressure would take on the order of a minute or more to change that much depending on weather conditions, vertical speed etc... It would be nice if there was a code change to accept a different type of MAP sensor, like a 1 BAR or something which would have better accuracy and precision.
